- To reduce confuse rename the parts of linuxbios bios that run from

ram linuxbios_ram instead of linuxbios_c and linuxbios_payload...
- Reordered the linker sections so the LinuxBIOS fallback image can take more the 64KiB on x86
- ROM_IMAGE_SIZE now will work when it is specified as larger than 64KiB.
- Tweaked the reset16.inc and reset16.lds to move the sanity check to see if everything will work.
- Start using romcc's built in preprocessor (This will simplify header compiler checks)
- Add helper functions for examining all of the resources
- Remove debug strings from chip.h
- Add llshell to src/arch/i386/llshell (Sometime later I can try it...)
- Add the ability to catch exceptions on x86
- Add gdb_stub support to x86
- Removed old cpu options
- Added an option so we can detect movnti support
- Remove some duplicate definitions from pci_ids.h
- Remove the 64bit resource code in amdk8/northbridge.c in preparation for making it generic
- Minor romcc bug fixes

1) Include llshell.inc in your northbridge Config file
2) In raminit.inc (or whatever), make a jmp out to low_level_shell, setting
a return label in %esp.
For example:
ram_set_registers:
mov $llshell_ret1,%esp
jmp low_level_shell
llshell_ret1:
/* Disable and invalidate the cache */
invd
mov %cr0, %eax
....
3) Optionally, comment out two lines in ramtest.inc:
5:
CONSOLE_INFO_TX_STRING($rt_toomany)
// intel_chip_post_macro(0xf1)
// jmp .Lhlt
otherwise, a ramtest failure will hang
4) build and flash as normal
If it worked, the speaker will beep, and you'll get a shell.
Type help or ? at the prompt for a list of commands.
